Do-it-yourself high-pressure hose repair for Karcher

In detail: do-it-yourself high-pressure hose repair for Karcher from a real master for the site my.housecope.com.

There is an equipment base in the tourist club Korbita. There is a well and a Karcher pressure washer. For three years the whole system worked without failures. And now, the Karcher hose broke. Many questions immediately arose. Where to buy a new hose? Where to run if Karcher is urgently needed?

We found out everything and share our experience! First, the Karcher hose is a high pressure hose and can be repaired. Secondly, Karcher high-pressure hoses can be repaired with your own hands, or you can do it in a specialized organization.

Do-it-yourself Karcher hose repair technology is very simple. First, cut the hose along the edges of the gap. Then we make the cuts even - either with special scissors, or with a machine, or with a cutting tool.

After that, we go to a special store for a fitting (a connecting tube along the inner diameter of the hose) and special power clamps. Ideally, put a pair of clamps on each side. Attention, simple clamps will not work!

Such a do-it-yourself hose repair has disadvantages. If the hose is used in the washing area, then the repair unit (clamps) will constantly cling to something, this is inconvenient.

Another minus. If you don’t have a fitting and a power clamp in your garage (in your warehouse), you still spend time looking for and buying a fitting of the desired diameter and clamps.

But there are also pluses. Such a repair of Karcher high pressure hoses will not be expensive. Especially if you need to lengthen the hose or make a few repair connections.

If you have little free time, you should turn to professionals. Pros . Repair the Karcher hose on site in 10 minutes. Repair carefully, the repair unit will not interfere with the work with the sink. Repaired on professional equipment and reliably.

Minuses . The cost of repair is 500-800 rubles for each node. That is, at a market value of a non-original, but acceptable in quality, Karcher hose of 2000-2500 rubles (autumn 2018), it makes sense to make repairs if you have a relatively new hose and no more than 2 damage. In other cases, it is worth thinking about a new hose.

We have compiled a list of organizations in major cities of the Central Federal District where you can repair the Karcher hose:

At least in a nutshell, but we need to talk about the reasons for the repair. In our case, the reason is this - the sink itself “shudders” at startup. The hose coming from the sink gradually rubbed against a sharp corner. But there may be other reasons - poor-quality hose material, mismatch of the operating pressure of the hose with the washing pressure, obsolescence of the hose, and others. Of course, all these reasons must be eliminated.

That's all! Keep your tool in good working order, keep enjoying your hands! Have a good day!

If the hose is torn off the flange, then you need to cut off the damaged section of the hose evenly, to the point where there are no extensions, cracks and undamaged cord.

Next, purchase the necessary flange and install it - fortunately, a large number of them are sold in auto stores and there is also a choice.The flange is inserted into the hose and simply crimped well with the help of a stop in the vise jaws and hammer blows from the third upper side.

If the damage is somewhere along the length of the hose, for example, a cut, a rupture, or something else, then we do exactly the same as in the first case, cut the hose and cut it to a whole, but here a connector of the desired diameter and a pair of clamps will help - just buy clamps not cheap, but good ones like those in the photo!

Repairing a high-pressure hose at Karcher is an almost hopeless business. If it is damaged in a straight section, crushed, chopped, and so on, then finding a double-sided Christmas tree branch pipe and compressing it at home on a hose is very problematic. You can do without buying a new (very expensive) hose only if it has begun to be torn off the outlet metal pipe. That is, the thread on the union coupling was torn off, and I don’t want to buy a new hose. Russian artisans do this:

A section of a rectangular pipe is taken, in my opinion, 45x25, the “CLIP” grip is carefully and thoughtfully cut out of it. With slots for the hose itself and for the pipe. I think it looks better in a photo. I repeat - if you don’t want to buy a new hose at all.

The design of the product, of course, is not a museum one, but it works properly. The connection may slightly dig, but this is not critical.

High-pressure hoses, more commonly referred to as high-pressure hoses (HPHs), are designed to create or absorb the working force that is transmitted under high pressure by liquids or gases pumped into them.

The main field of application of high pressure hoses is hydraulic and pneumatic systems of various devices and mechanisms. Outside of industrial production, motor vehicle owners most often deal with high-pressure hoses, these are power steering hoses (Power Steering), and those who use high-pressure pumps, for example, the most common Karcher brand in our country.

The design of the high pressure hose is due to the need to withstand internal pressure, which can reach up to several hundred atmospheres.

In addition, the inner surface of the high-pressure hose must be impervious to the media being transported. Therefore, its lower layer is made of oil and petrol resistant rubber or synthetic rubber.

For the manufacture of the upper, thicker layer of the high-pressure hose, wear-resistant rubber is used, which, if necessary, is supplemented with thermal protection in the form of a corrugated coating, metal or polymer.

A metal wire is wound in several layers between the upper and lower layers of rubber, thanks to which the hose receives the necessary rigidity and strength. Layers of wire are interspersed with thin rubber films.

Depending on the method of winding the wire, there are two types of high-pressure hoses:

  1. Coiled. In the production of this type of hose, the coils of wire are wound in even rows.
  2. Braided. In this case, the coils are wound at an angle to the axis of the hose so that the coils of the previous layer cross with the coils of the next layer of wire. Braided hoses are more durable and able to withstand more pressure than winding hoses.

In addition to the wire, textiles can act as an internal rigid frame.

The number of wire layers and the thickness of the rubber layers are set by standards that determine the scope of one or another type of high pressure hoses.

To fix the hoses in place, fittings (tips) are mounted at their ends, which are of the following types:

Fittings are fastened to the ends of the hose using compression couplings, which are pressed on special machines.

Depending on the type of shank, fittings are classified into series:

  1. Universal. This series can be used in all high pressure hoses except coil type hoses.
  2. Interlock. The series is used for winding sleeves.

When installing fittings of this type, it is imperative to remove both layers of rubber, inner and outer.
